I'm using BT Infinity and have no complaints TBH. Never had any drop off in performance, whereas Virgin was always going wrong when I had. Although when I had Sky broadband that didn't see to go wrong much either.

We had BT at our old home and it was perfect. Now have Sky and it's terrible, I think we're in the area affected by crap speeds since they've been selling a load of the sky boxes in London with the anytime feature so the broadband gets so bogged down at the weekend.

Be is owned by O2: i'd be surprised if they sold to Sky. I'm with O2 and have never had any problems... Mind you, that might be because their router station is next to my house! Be was the same connection rate, but slightly more expensive- I'm on 20Mbps for £13.

I'm a bit lucky getting Virgin - my village is on the edge of an old Telewest cable area so contention isn't an enormous issue (since there aren't many people in the village) but the connection speed is as good as in a bigger town.
